-- Classifiers

--

-- Classifier allows multiple classifier elements, of same or

-- different types, to be used together.

-- A classifier must completely classify all packets presented to

-- it. This means all traffic handled by a classifier must match

-- at least one classifier element within the classifier,

-- with the classifier element parameters specified by a filter.

-- It is the PDP's responsibility to create a _catch all_ classifier

-- element and filter that matches all packet.  This _catch all_

-- classifier element should have the lowest Precedence value.

--

-- If there is ambiguity between classifier elements of different

-- classifier, classifier linkage order indicates their precedence;

-- the first classifier in the link is applied to the traffic first.

--

-- Each entry in the classifier table represents a classifier, with

-- classifier element table handling the fan-out functionality of a

-- classifier, and filter table defining the classification

-- patterns.
